Step 1: Alternate framing: watershed-based development logic:
The programme is built on the watershed as its planning unit — treating an entire natural drainage area together so that rainwater is conserved, soil erosion is checked, and groundwater recharge improves across the whole watershed rather than piecemeal.
Step 2: Trace the chain of benefits:
Better water conservation at the watershed level → more reliable irrigation and drinking water → more stable crop yields and fodder supply → reduced distress migration and improved rural incomes in otherwise drought-vulnerable regions.
Step 3: Final Answer:
By adopting watershed-based conservation as its core strategy, DPAP strengthens water and soil resources across drought-prone regions, leading to more stable agriculture, reduced distress migration, and sustainable rural development.
